The purpose of the study was to investigate the changes in glycosaminoglycans of the gingiva during experimental periodontitis induced by placing a silk ligature below the gingival margin of dog molars. Incorporation of ~3H-glucosamine into the gingiva was determined autoradiographically. The gingiva was collected at 7,21,60 and 90 days and cultured in vitro in the presence of ~3H-glycosamine. The autoradiographs showed a epithelial location of the silver grains in all gingival epithelia. The location...

The purpose of the study was to investigate the changes in glycosaminoglycans of the gingiva during experimental periodontitis induced by placing a silk ligature below the gingival margin of dog molars. Incorporation of ~3H-glucosamine into the gingiva was determined autoradiographically. The gingiva was collected at 7,21,60 and 90 days and cultured in vitro in the presence of ~3H-glycosamine. The autoradiographs showed a epithelial location of the silver grains in all gingival epithelia. The location was intercellular in all epithelia. The results suggest that ~3H-glucos-amine incorporation by the epithelium is greater compared with the connective tissue and markedly more rapid metabolic turnover of epithelial glycosaminoglycans.

在狗磨牙的龈沟处用丝线缝合结扎引起实验性牙周炎,再分别取下结扎7、21、60、90天的牙龈组织。把~3H葡萄糖胺作为示踪物在体外培养,制成自体放射照片标本,摄取~3H-葡萄糖胺的部位显示银色颗粒。其结果是各时期的口腔上皮,龈沟上皮、结合上皮都存在银粒子,而主要存在上皮细胞间,结缔组织内存在微量。由此可见,上皮与结缔组织相比,上皮~3H-葡萄糖胺摄取量高,代谢速度显著快。

Since June, 1988, 36 cases with partial anodontia have been implanted with bioactiveglass-ceramics (BGC) teeth and the therapeutic efficacy have showed satisfactory. The causes for 39 teeth deletions of the 36 cases were traumatic fractures of the roots (15 cases), residual roots (13 cases), traumatic deletion (4 cases), long-standing chronic periapical periodontitis (3cases) and carious dens extraction (1 case). The youngest of the cases was 17 years, the oldest 26 and the average was about 19. The tooth deletions...

Since June, 1988, 36 cases with partial anodontia have been implanted with bioactiveglass-ceramics (BGC) teeth and the therapeutic efficacy have showed satisfactory. The causes for 39 teeth deletions of the 36 cases were traumatic fractures of the roots (15 cases), residual roots (13 cases), traumatic deletion (4 cases), long-standing chronic periapical periodontitis (3cases) and carious dens extraction (1 case). The youngest of the cases was 17 years, the oldest 26 and the average was about 19. The tooth deletions were located as follows: The roots of BGC teeth, which were made in Huaxi Medical University, were prepared into spiral or cylindrical forms. The BGC teeth were implanted after dens extraction immediately (16cases) and postponement (20 cases). The diameters of the BGC teeth implanted were 3.3 mm (6 teeth), 3.5 mm (15 teeth), 3.7mm (13 teeth) and 4.0 mm (five teeth) respectively. The lengths from the root implanted to the gingival margin were 11.0mm (16 teeth), 13.0mm (11 teeth), 1-4.0 mm (8 teeth) and 15.0 mm (4 teeth) respectively. The duration of the implants was from 2 to 44 months. Till now all the BGC teeth implanted have been alive. After the implantation the tooth morbidity measure showed that 27 teeth of 26 cases and 7 teeth of 6 cases recovered normal occlusal function within 3 and 6 months respectively. Now 4 teeth of 3 cases have odontoseisis Ⅱ°, one tooth Ⅲ°. These teeth which have odontoseisis had distinct degrees of pain when chewing, but after occlusal adjustment the pain disappeared.

Abstract In this study,131 patients who have 180 implant dentures were investigated clinically after treatments for 1 ̄5 years. It was shown that effects on various types of superstructures fabricated were satisfatory by meatal-porcelain.metal-resion or metal materials.The ideal postion of the maragin of the retainer crown to gingival margin was 0.5 ̄2mm. The blte force of anterior implant dentures were found to be significantly lower than that of natural teeth.The bite force values of posterior implant dentures were near or even higher than that of natural teeth. Masticatory effeciency was not significant different between partial and complete fixed implant dentures. Five implant dentures(three crowns and two bridges)were failed as a result of defect of the strength of abutment teeth or the prosthesis materials.The principles for the design of superstructures and the choice of prosthesis materials have been discussed.

作者对骨内牙种植体上部结构修复后1~5年患者计131例180件进行临床复查,结果:金一瓷、金一塑、金属材料制成的各类型上部结构效果均理想;固位体冠边缘位于龈缘上0.5~2mm为佳;前牙种植义齿 力值明显低于正常天然前牙 力值,后牙种植义齿 力值接近或超过天然后牙;咀嚼效能、部分及全颌固定种植义齿两者无明显差异。失败的5件(2.8%)种植义齿(冠3件、桥2件)与基牙组合、修复材料强度有关。本文还对修复材料、上部结构设计等进行了讨论。
